Further according to the the curvedbars 16. The chain links 21 are invention the links of the lower chainare provided with guide rollers 23,which run in 50 provided with springactuated clamping guides 22. The drive of the machine is effected bybelt pulleys 35. A bevel wheel 37 and a spur wheel 38 are keyed on thedriving shaft 36. The spur wheel 38 transmits its rotation to the shaft40 by means of a spur wheel 39. On the shaft 40 a spur wheel 41 iskeyed, which moves forward, the upper chain 4 and lower chain 2 throughspur wheels 43 and 42. A shaft 45 is rotated by the bevel wheel 37 and abevel 44, and the movement of shaft 45 is transmitted to shaft 49 bysprocket wheels 46, 47 and a chain 48. The cam 33 is keyed on the shaft49 and imparts a reciprocating movement to the chain housing 50 throu 'hthe cam rod 34. The upper chain 4 is stretched over the chain rollers 14and 15 in the chain housing 50. The drive of the chain rollers 15 iseffected by a square shaft 51 from the spur wheel 43. The square shaft51 therefore performs a reciprocating movement in the square bore of thespur wheel in addition to the rotary movement. A bolt 52 connects thecam rod 34 to the chain housing 50. The drive of the wheel 7 istransmitted from the spur wheel 42 onto a spur wheel 53. The drive ofthe rollers 10 and 11 is transmitted through sprocket wheels 54, 55 andchain 56 onto spur wheels 57. The drive of the conveyor band 31 iseffected from the driving shaft 36 through sprocket wheels 58, 59 andchain 60. 61 and 62 are the walls of the frame, 63 connecting rods, 64is a discharge plate, 65 are bolts which open and close the grippers 6by their radial displacement. 66 and 67 are stationary cams which servefor controlling the bolts 65. The cams 66 and 67 are fixed on the wall62 by four angle brackets 68.

The band of mass gripped by the lower chain 2 is cut into pieces duringits forward movement by means of the reciprocating cutting knives 5,which are gradually pressed downwards by the curved bars 16. The knivesare then moved vertically upwards by the pressure of the springs 19, sothat the cut pieces of mass lie freely on the lower chain 2, being onlyheld by the clamping jaws 3. As soon as the chain links bear on thepitch circle circumference of the chain roller 13 of the lower chain 2,the chain links move apart, and the still existing adhesion of theindividual pieces of mass is loosened. A wheel 7 with grippers 6 isfitted at the reversin point of the lower chain 2. The grippers 6 enterthe gaps formed between the spread chain links and grip the pieces ofmass 8. At the same time the clamping jaws 3 arranged on the lower chain2 disengage and release the pieces of mass 8. During the furtherrotation of the wheel 7 the pieces of mass 8 are deposited through thedisengagement of the grippers 6 onto the conveyor band 31 with conveyorshafts 32 situated thereunder.

I claim 2- 1. A machine for making cream caramels and similar caramels,comprising in combination a lower chain adapted to serve as conveyorband for the sugar mass fed thereto in the shape of a calibrated band,an upper chain arranged above and rotating at the same speed as saidlower chain, means for imparting to said upper chain a reciprocatingmovement in transverse direction during its rotating movement,vertically shiftable knives on said upper chain, and stops adapted toshift said knives.

2. A machine as specified in claim 1, comprising in combination with thelower chain, composed of links, clamping jaws on said links, springsacting on said jaws, and guide bars adapted to guide said jaws.

3. A machine as specified in claim 1, comprising in combination with thelower chain, a wheel provided at the reversing point of said chain,controlled grippers on said wheel adapted to take the severed piecesfrom said lower chain, and a conveyor band arranged under said wheeladapted to receive the sevcred pieces removed from said lower chain bysaid grippers.

In testimony whereof I affix my signature.

MAX PGNISCH.
